'WILLIAM H. LAZEAR, OF BERKELEY, CALIFORNIA.

TOY WAGON.

Application filed February 7, 1921.

To aZZ whom it may concern Be it known that 1, WILLIAM H. LAZEAR, a citizen of the United States, and resident of Berkeley, county of Alameda, and State of California, have invented a new and useful Toy Wagon, of which the following is a specification.

The present invention relates to improvements in carriages and its object is to provide a carriage the axle of which will impart a rocking motion to its body. A further object of my invention is to accompllsh this rocking motion without alternatingly increasing and decreasing the power necessary to move the carriage by introducing a balancing weight adapted to overcome the tendency of the rising body to oppose and of the falling body to assist the forward or backward motions of the car the resultant being a constant, even pull or push.

I attain these objects by means of the mechanism illustrated in the accompanying drawing, in which Figure 1 is a side view of a carriage having my rocking device attached thereto, Figure 2 an end view of part of the same, Figure 3 a sectional View of an axle and wheel connection, Figure 4 a rear view of a carriage showing a modified form of my invention, and Figure 5 a' side view of a carriage wheel showing a further modification of my invention.

Referring. to the drawing more specifically (1) indicates a carriage, which may be of any design, and may have any kind of drive attached to it. In the drawing the drive is shown to consist of two foot levers (2) engaging, by means of two connecting rods (3), two oppositely arranged cranks (4) in the rear axle The manner of driving the carriage having no bearing on my invention, the carriage may be made to be pushed, or pulled or moved in any other manner.

The two wheels (7) are eccentrically and rigidly mounted on the axle I preferably use for this purpose axle ends of square cross-section. If the wheels are placed on the axle in a corresponding position, the

body is confined to a longitudinal rocking motion, and if there are placed one hub above and one hub below the center of the Serial No. 443,044.

wheel the body will combine a longitudinal with a lateral rocking motion, imitating somewhat the rocking motion of a boat on the waves.

Figure 1 shows the hubs of the rear wheels arranged eccentrically, so that each turn of the rear wheel alternately raises and lowers the body (8). The fact that the hub is arranged eccentrically, would tend to alternately decrease and increase the power necessary to drive the carriage since during one half of the turn it would have to lift the body besides driving the carriage, while during the other half of the turn the weight of the carriage would assist in driving the car. To overcome this undesirable feaure I provide a weight (9) attached to the rim (10) of the wheel, its center of gravity lying on a wheel diameter going through the eccentric, so that the center of the wheel lies between the weight and the eccentric. This way the center of the wheel may be considered the fulcrum of a' lever, one short arm, that between the center of the wheel and the eccentric, supporting a portion of the weight of the body and a long arm supporting the weight on the rim, and the two weights should be in versely proportional to the respective lengths of the two arms. If arranged this way, it is clear that at any time during the revolution of the wheel the weight on the arm will counterbalance the weight of the rising and the falling body, thus securing a smooth drive.

Figure 4 shows a modification of my invention in which the axle is secured in the center of the wheels and the rocking of the body brought about by a crank-like bend in the axle, as shown at (11), the body being rotatably secured to the bent part of the axle.

Figure 5 shows another modification, in which the wheel is equipped with an ordinary central hub (14) and an eccentric hub (iii), which two may be used interchangea y.

It is understood that my device may he used on the front axle as well as on the rear axle, and also on both axles. In the latter case the hubs may be arranged to lift and ported over the axle, means for imparting rotary motion to the axle, two Wheels hav- 111;; hubs in eeoentrieal relation to the rims 10 adapted to fixedly engage the ends of the axle, a Weight attached to the rim of each Wheel adapted to counterbalance the Weight of the hub and the body of the Wagon on the center of the Wheel as a fulcrum for equalizing the force to be applied for driving the Wagon.
